Heavy metals discharged from various industries like electroplating, leather tanning, paint, textile and dying units are the primary cause of water pollution [1]. They pose serious threats to public health and environment due to their high toxicity, bio accumulative and non-biodegradable behavior [1,2]. Therefore, Water purification is emerging as a critical need for the researchers owing to th...

Introduction: One of the heavy metals is chromium which is used in trivalent and Hexavalent oxidation state in industries such as, glass, ceramic, tannery, leather especially in electroplating industries. Hexavalent Chromium has proven several health hazards such as a carcinogen. The aim of this study was to investigate the efficiency of Melia azedarach ash in the removal of hexavalent chromium...

Abstract – In this report, time-dependent carrier concentration in electrolytic cells, due to some basic periodic shapes of excitation signal, has been studied. Exact analytical solutions for step, sinusoidal and periodic pulse reverse inputs are derived. The effect of frequency, forward and reverse amplitudes, and duty cycle are investigated. An analytical solution of the model is obtained as ...
